(1) The public water system or its agent's
certification.
The Director relies upon the professional judgment of the
registered professional engineer who certifies that the hydraulic analysis and
evaluation have been done properly and that the flow and pressure requirements
have been met. The public water system or its agent shall, after a thorough
review, submit a document to the Director certifying that the following
requirements have been met:
(a) the
hydraulic model requirements as set forth in rule
R309-511-5;
(b) the appropriate demand requirements as
specified in this rule and rule R309-510 have been used to evaluate various
operating conditions of the public drinking water system;
(c) the hydraulic model predicts that new
construction will not result in any service connection within the new expansion
area not meeting the minimum distribution system pressures as specified in
R309-105-9;
(d) the hydraulic model predicts that new
construction will not decrease the pressures within the existing water system
such that the minimum distribution system pressures are not met, as specified
in
R309-105-9;
(e) the calibration methodology is described
and the model is sufficiently accurate to represent conditions likely to be
experienced in the water delivery system; and,
(f) identify the hydraulic modeling method,
and if computer software was used, the software name and version
used.
(2) The format of
the public water system or its agent's submission.
The public water system or its agent shall submit to the
Director the following documentation:
(a) the certification as required in
R309-511-6(1). The certification shall be signed, dated, and stamped by a
registered professional engineer, licensed to practice in the State of
Utah;
(b) a Hydraulic Model Design
Elements Report (see
R309-511-7). The document shall be signed, dated, and stamped by a registered
professional engineer, licensed to practice in the State of Utah;
and,
(c) for community public water
systems, the water system management shall certify that they have received a
copy of input and output data for the hydraulic model with the simulation
showing the worst case results in terms of water system pressure and
flow.
(3) The submission
of supporting documentation.
The public water system or its agent shall submit a System
Capacity and Expansion Report (see
R309-511-8) if requested by the Director. The document shall be signed, dated, and
stamped by a registered professional engineer, licensed to practice in the
State of Utah.
